Summary for Patent: 6,649,180

Title: Hard capsule formed of cellulose ether film with a specific content of methoxyl and hydroxypropoxyl groups
Abstract:A cellulose ether film is formed of a composition comprising a cellulose ether as a base in which some of the hydrogen atoms of cellulosic hydroxyl groups are replaced by alkyl groups and/or hydroxyalkyl groups, a gelling agent, and a gelling aid. The total content of alkoxyl and hydroxyalkoxyl groups in the cellulose ether is limited to 23-37.6% by weight, which is effective for preventing the gelling aid from precipitating out and maintaining a favorable outer appearance during long-term storage.
